A low gas-permeable hose has an inner rubber layer, a reinforcing multilayer portion including a first reinforcing layer and a second reinforcing layer on an outer side of the inner rubber layer, an outer rubber layer on an outer side of the reinforcing multilayer portion, a resin layer defining an innermost layer; and a barrier layer on an inner side of the inner rubber layer and on an outer side of the resin layer. The barrier layer is a resin membrane of polyvinyl alcohol. The reinforcing multilayer portion has a cooperative reinforcing structure for ensuring the second reinforcing layer of reinforcement to the first reinforcing layer.
